I've been coding with pycharm and was thinking we should follow standards. One thing I've noticed is by default Pythonista uses tabbed indenting where in https://www.python.org/dev/peps/pep-0008/ its a 4 space indent that is recommended.
You can use 4 spaces in Pythonista if you like, there's a setting for that (under "Indentation"). The reason Pythonista uses tabs by default (and a tab width of 2 spaces) is mostly that it tends to be used on very small screens...
The soft tabs and show mixed indentation options in Pythonista give you the best of both worlds. I always keep them both turned on. It is kind of anachronistic that all the example scripts use tabs.
